Brocade Fabric OS Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 61)

All Fibre Channel ports on all logical switches are taken offline. If the logical switches are in fabrics,
the fabrics are reconfigured.
NOTE
After a chassisDisable , if you want to do an haFailover , you should wait at least 30 seconds.
Enabling a chassis
Enabling a chassis enables all Fibre Channel ports on all logical switches in the chassis. The chassis is
enabled by default after it is powered on and switch initialization routines have finished. You must re-
enable the chassis after making fabric-wide configuration changes or running offline diagnostics.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the chassisEnable command.
switch:FID128:admin> chassisenable
For all logical switches in the chassis, all Fibre Channel ports that passed Power On Self Test
(POST) are enabled. If any of the logical switches have inter-switch links (ISLs) to a fabric, it joins the
fabric.
Switch and Backbone shutdown
To avoid corrupting your file system, you must perform graceful shutdowns of Brocade switches and
Backbones.
Warm reboot (also known as graceful shutdown ) refers to shutting down the switch or platform by way
of the following instructions. Cold boot (also known as a hard boot ) refers to shutting down the switch
or platform by suddenly shutting down power and powering on again.
Powering off a Brocade switch
Use the following procedure to gracefully shut down a Brocade switch.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the sysShutdown command.
3. Enter y at the prompt.
switch:admin> sysshutdown
This command will shutdown the operating systems on your switch.
You are required to power-cycle the switch in order to restore operation.
Are you sure you want to shutdown the switch [y/n]?y
4. Wait until the following message displays:
